.Application filed September 1U, 1913. Serial No. 789,092.

.To all whom t may conce/rn.' Be `it known that I, 'ASA Logansport, inthe county of Cass and ftateof Indiana, have invented .new and usefulimprovements in Reinforcedoncrete Ties,

.of which ythe'following'is a specification.

This invention is an improved reinforced concretetiehfor railroads, .theobject of the invention being to provide an improved tie of thischaracter which may be manufactured at minimum cost, is exceedinglystrong and durable, .and which` provides mgans for directly fastenlngthe rails thereon` and for adjusting the rails, the inventionconsistingin theconstruction, combination and arrangement of deviceshereinafter described and claimed.

`In the accompanying drawings: Figure l is a perspective View of areinforced con crete tie constructed in accordance with my invention.Fig. 2 is a 'verticallongitudinal Sectional view of the same. Fig; 3 isa plan of the blank from which the facing plate of the tie isconstructed. Fig. 4l is a vertical transverse sectional View of-myimproved reinforced conerete tie on a yplane near one of the railsf Fig.5 is a'similar View of the same on a-plane lbetween the Fig. (l is adetail perspective view of one of the clamping jaws.

In' accordance with vmy invention I provide a facing late 1 to coverthenbody 2 of the tie, this Yacing plate being preferably made of ironor steel and being formed from a single blank which corresponds in widthwith the tie and is somewhat longer than the tie sol that .its ends 3may be bent at the. points indicated by the dotted lines 4' in Fig. 3and adapted to bear on and cover the ends of the tie. The end portions 3of the facing plate'are formed at their upper sides,

`where they join the main portion of the facing plate with oblongrectangularopenings 5 and the, main or top portion of the facing plateis formed with a-centrally arranged longitudinal sl'ot 6 which extendsto and'connectsthe said openings, and at the center of the saidslotyonopposite sides thereof7 .arenotches 7 which form an open ing inthe center ,of the facing plate.

A channel plate 8 which is cross sectionally rectangular and the sideWalls of which .are provided With outwardly' extending fianges 9 isarranged under the center of the Imain portion of the facing plate andunder E. Pnnarn'rnn, a; `citizen of the United States, residin at" theslot G thereof, withits ends coincident with the openings' andtheflanges 9 ofI this ychannel plate aresecured to the main portion ofthe facing plate by means `of rivets -or other suitable devices 10.Hence the channel plate forms a longitudinal groove or channel widerthanand below the slot 6 of the facing plate which extends from end toend of the tie, the sides Iofthe slot G formed by the facing plateoverhanging opposite sides of the channel and forming flanges 1l and thesaid flanges, are corru-A gated transversely, tho said series of corru-.gations extending `from end `to end of the tie and being indicated at12. It willQ/be understood that the channel plate not only forms alongitudinal channelin the upper side of the tie but also greatlystrengthens and reinforces the facing plate below and. at the sides ofthe slot 6 in the latter.

'lhe-downtuined ends 3 of the facing plat'l are connected b tie rods 14which extend :from end to en( of the tie and through tlfc concrete bodythereof and also extend through a pair of transversely arranged braceIplates 15 which are in contact with cach other and the upper sides ofwhich are provided with outturned anges 1G which are riveted orotherwise suitably secured to the facing plate as at 17. v These braceplates also form a break line across the center of the concrete body ofthe tic and serve to face the two members or sections of the concretebody of the tie so as to prevent the said concrete members from rubbingagainst each other under the stresses imosed thereon. The concrete bodyof the tie 1s molded so that the tie rods and the channel plato areembedded therein. I also provide rail securing devices for fastening thebases of the rails on the tie. Each of these rail securing devicescomprises a bolt 18, a clamp jaw 19, a nut 20 and a lock n ut 2l. Thebolts 18 are arranged vertically with their Shanks extending up throughthe slot 6 of the facing plate-fand their heads 2Q,

The clamping jaws 19 are wedge shaped longitudinally so that their innerends are adapted to bear on the base flanges of the rails, and the saidclamping jaws are provided on their under sides1 with; medially arrangeddownwardly extending tongues 23 which enter the slot G. Theg-niits '20andl' l shown as a fluted spring steel plate, is placed spring taking upthe shock and permitting bet-Ween the brace plates 15 to .act as aspring when Weight is imposed on, the tie and enable the brace plates tomove toward each other under such stress, the cushion or the tie toyield slightly to the stress.

v Having thus described my invention, I claim:

1. A reinforced concrete tie comprising a concrete body, a'facing platethereon having downturned end portions bearing against the ends of thebody, tie rods extending through the concrete body, embedded there- 40in and secured to the vdownturned ends of the facing plate and a pair oftransversely arranged brace plates in the body of the tie and secured tothe facing plate..

3. A reinforced concrete tie comprising a concrete body, a facing platethereon having downturnd end portions bearing against the endsl of thebody, tie rods extending through the concrete body embedded therein andsecured to the downturned ends of the facing plate, a pair oftransversely arranged brace' plates in the body of the tie and acushioning element between said brace plates.

In testimony whereof I afi-iX my signature in presence of two witnesses.
